CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 660,780, dated October 30, 1900.

Application filed April 30, 1900. Serial No. 14,865. (No model.) i

To all whom it may conc n: of the slot when the block has reached oper- Be it known that 1, WILLIAM MCCONWAY, ative position in front of thetail of the acitizen of the United States,residing atPittsknuckle. The locking-block is provided on burg, in the county of Allegheny and State of its rear side with one or more fingers 11, with Pennsylvania, have invented or discovered which a head 9 on the lifting-stem 10is adapt 55 certain new and useful Improvements in Cared to engage and shift the locking-block to Couplers, of which improvements the followunlocking position. The stem 10 extends up ing is a specification. through the box or shell 5 and is adapted to The invention described herein relates to be connected to any suitable form of 1nech- 10 certain improvements in car-couplers of the anism whereby the coupler may be unlocked 6o Janney or swinging-hook type, and has for from the side of the car. These parts are so its object the provision of means whereby the arranged that when the stem and head are hook or knuckle locking device may be held raised they will engage books 11 and draw the in inoperative position while the knuckle is locking-block back to unlocking position, as

15 closed, but will be released from such inopclearly shown in Fig. 3. In order to hold ()5 erative position by the opening movement of the locking-block in this position, the liftingthe knuckle. head 9 is provided with a prop or arm 12 at The invention is hereinafter more fully deone end arranged to normally extend down scribed and claimed. at one side of the locking-block, and a shoul- In the accompanying drawings, forming a der or abutment 13 is formed on the coupler- 7:. part of this specification, Figure l is a sechead adjacent to the path of movement of t-ional plan view of a coupler in locked posithe prop, so that when the head 9 is raised tion having myimprovement applied thereto, the prop or arm 12 will be shifted to one side the plane of section being indicated by the onto the abutment or step 13. In order to line I I, Fig. 3. Fig. 2 is a sectional elevainsure the lateral movement of the lower end tion of the same in unlocked position, the of the arm or prop, one of the hooks 11 is plane of section being indicated by'the line made a little shorter than the other hook,

II II, Fig. 1; and Fig. 3 is a view showing the and the stem 10 is preferably formed at an coupler-head in section and the knuckle and angle to the head 9, so that when the head is 30 locking mechanism in elevation, the knuckle raised it will be given a tip, as shown in Fig. being closed, but unlocked. 2, and thereby throw the lower end of the My improved coupler consists of a head 1, prop or arm out away from the locking-block knuckle 2, and swinging locking-block 3, said and onto the step or abutment 13, and thereparts being constructed and arranged subby support the looking-block in inoperative 35 stantially as shown and described in applicaposition. In order that the locking-block tion, Serial No. 6,236, filed February 23, 1900. may be released, so as to engage the tail of the As set forth in said application, the lockingknuckle when the latter is closed, a shoulder block 3 is loosely mounted on the pin 4, pass- 14 is so arranged on the tail of the knuckle ing through a box or shell 5, forming an upthat when the latter is open after being un- 0 per side of the coupler-head, said box also looked this shoulder will strike against the serving as a stop or shoulder for limiting, by prop or arm 12 and push it off the supportingbearing on the end of the sill of the car, the step abutment 13, thereby permitting the inward movement of the coupler-head. The locking-block to drop against the tail of the forward movement of the lockingblock is knuckle, so that when the latter is closed it 5 limited byasuitable stop-such,for example, will swing into operative position in front of as that shown--consisting of a slot 8, formed the tail of the knuckle, as shown in Fig. l. in the bottom of the couplerhead in such po- It is preferred to so proportion the lockingsition that a lug 7 on the lower end of the block and the head 9 that when the head 9 locking-block will enter said slot, and its is released and the locking-block swings to 50 movement will be arrested with the front wall operative position the former will drop down" 00 and Wedge itself between the wall of the coupler and the rear face of the lockingblock, thereby holding the latter firmly in looking position.

I claim herein as my invention- 1. In a car-coupler, the combination of a swinging hook provided with a tailpiece, a pivotallymounted locking-block adapted to move automatically into the path of movement of the tail of the knuckle, means for shifting the locking-block to inoperative position, a shoulder or step on the coupler-head, an arm or prop adapted to be supported by the step and hold the block in unlocked position and means for shifting the lower end of the arm or prop laterally with respect to the coupler-head onto the step, substantially as set forth.

2. In a car-coupler, the combination of a swinging hook provided with a tailpiece, a pivotally-mounted locking-block adapted to move automatically into the path of movement of the tail of the knuckle, a shoulder or step in the coupler-head at one side of the path of movement ofthe tail of the knuckle, an arm or prop adapted to he supported by the step and hold the locking-block in unlocked position, and a shoulder projecting from the rear end of the tail of the knuckle and adapted to push the prop laterally with respect to the coupler-head off of the step,

substantially set forth.

3. In a car-coupler, the combination of a swinging hook provided with a tailpiece, a pivotally-mounted locking-block adapted to move into the path of movement of the tail of the knuckle, a lifting-head adapted to shift the block to inoperative position, a step on the coupler-head, and an arm or prop on the lifting-head adapted to be shifted away from the locking-block onto the step when the head is raised, substantially as set forth.

4. In a car-coupler, the combination of a swinging hook provided with a tailpiece, a pivotally-mounted locking-block provided with fingers, a lifting-head adapted to engage the fingers on the locking-block, a step on the coupler-head, an arm or prop on the lifting-head adapted to be shifted onto the step when the head is raised, and a project-ion on the tail of the knuckle adapted when the knuckle is opened to force the prop off of the step, substantially as set forth.

In testimony whereof I have hereunto set my hand.

WILLIAM MCCONWAY.
